Abstract

A conjugate filament is produced by feeding two liquids 1 and 2 to a common pre-spinning orifice 5 from opposite sides of a partition 4 and then feeding the double stream (Fig. 3) and an annular stream of liquid 2 from a reservoir 6 to a common spinning orifice 7 to produce a filament of Fig. 1 cross-section. According to Fig. 5, filters (13, 14 and 17) for the liquids are provided in the spinneret assembly. Melt, wet or dry spinning may be employed. Liquid 1 may be polyethylene oxybenzoate or a copolymer of nylon-6 and polyhexmethyleneisophthalamide and liquid 2 may be nylon-6.
